Abstract
An illumination system, including a housing, a first light source, a second light source, a polarization beam splitting element, and a heat dissipation module, is provided. The first light source and the second light source are disposed in the housing and are respectively configured to provide a first beam to the polarization beam splitting element along a first optical axis and a second beam to the polarization beam splitting element along a second optical axis. A portion of an inner surface of the housing has a light absorption region. The light absorption region is configured to absorb the first beam that is not reflected by the polarization beam splitting element and the second beam that does not penetrate the polarization beam splitting element, so as to convert them into heat. The heat generated by the light absorption region is dissipated by the heat dissipation module.
